九江城区校园室内灰尘中邻苯二甲酸酯污染特征研究

Study of the Distribution Characteristics of Phthalate Esters in Urban Indoor Dust of Jiujiang Campus of Different Size Fractions

城区室内灰尘是生态系统重要组成部分,城市室内大气干湿沉降和人为排放等过程都会污染城区室内灰尘。因此,研究室内灰尘污染状况对探寻污染来源、评价污染现状及预测对城市生态系统的影响具有重要的现实意义。文章以美国环保署(USEPA)8061系列分析方法为基础,在严格的质量保证(QA)/质量控制(QC)条件下,系统研究了九江学院宿舍区、实验区及办公区等不同功能区域17个样品中16种邻苯二甲酸酯(PAEs)的组成特征、含量水平,探讨了城区校园室内灰尘PAEs的污染来源,并对九江市城区校园室内灰尘PAEs的污染影响进行了初步评价;为PAEs多介质归趋研究和区域风险分析提供理论依据。

Urban indoor dust is the important part of the ecosystem and the kind of dust is the the ultimately place which gather urban indoor environment. Therefore, the result would make a great contribution to understand the pollution status, contamination resources and the affection to the ecosystem of urban indoor dust. The composition and distribution characteristics of 16 PAEs in 17 indoor dust samples, which collected from urban indoors in dormitory area, experiment area and office area of campus of Jiujiang University. The composition and distribution characteristics of 16 PAEs in samples were both investigated using GC-FID and GC-MS under quality assurance （QA） and quality control （QC） based on the U.S.EPA 8061 series methods.
